Solve for the concentration of the column at time t, returning the vector of concentration representing the concentration profile of column over its length.
Solve for the concentration of the column at time t, returning the vector of concentration representing the concentration profile of column over its length. This method uses an explicit finite difference technique to solve the PDE. L-W is the Lax-Wendroff scheme which has second-order accuracy.

The
FirstOrderPDE
class is used to solve first order partial differential equations like the Advection Equation. Let 'u(x, t)' = concentration in a fluid with velocity 'v' at position '0 <= x <= xm' and time 't' > 0. Numerically solve theAdvection Equation: u_t + v(x, t) * u_x = 0 with initial conditions u(x, 0) = ic(x) boundary conditions (u(0, t), u(xm, t)) = bc
